Timeon Model of Ouark and Lepton Mass Matrix: Professor R. Friedberg and I proposed that T violation in physics arises from a pseudoscalar interaction with a new ←Spin 0 field, called timeon. For quarks, the model gives a compact three-dimensional geometric picture consisting of two elliptic plates and one needle, describing the 10 observables: six quark masses, three Eulerian angles and the Jarlskog invariant. For leptons, the model predicts two relations between the corresponding three Eulerian angles and the Jarlskog invariant. Explicit Convergent Iterative Solutions of the Schroedinger Equation: Together with Professor R. Friedberg and Professor W.Q. Zhao (CCAST), I have developed a new rapidly convergent iterative procedure to derive the ground state and low-lying excited states for a class of Schoedinger Equation. These include the solutions for a sombrero-shaped potential in any space dimension and arbitrary angular momentum. Higgs Boson as a Composite: In a recent paper with Professor R. Friedberg, I examine the possibility that Higgs boson may be a composite, not an elementary particle. Thus, the theoretical description of the analytical properties of Higgs may be quite different from that of an unstable elementary particle. The experimental search for Higgs should then be also different from the usual detection techniques for an elementary particle.
